TL;DR: Essential lignin-degraded products, oil (liquid), char (solid), and gas were obtained, and their yields were directly influenced by reaction conditions, as well as indirectly from the results of atomic H/C and O/C of the oils.

TL;DR: Size and age structure analysis, dated past disturbances, treefall replacement patterns, and spatial pattern analysis were used to reconstruct the developmental history of two old-growth Nothofagus fusca/N.
Abstract: Size and age structure analysis, dated past disturbances, treefall replacement patterns, and spatial pattern analysis were used to reconstruct the developmental history of two old-growth Nothofagus fusca/N. menziesii stands, South Island, New Zealand. Diameter and height class distributions suggested that N. menziesii was replacing N. fusca, however, stand history reconstruction analysis showed that both species had regenerated intermittently after small-scale disturbances. Although large-scale disturbances such as blowdowns may occasionally generate even-aged stands, gap-phase regeneration maintains the forests in compositional equilibrium. In the absence of other competing tree species and understorey plants the two species appear to coexist by way of different life history strategies, where one species (N. menziesii) has low juvenile mortality and the other (N. fusca) has faster height growth rates and greater longevity and adult survivorship.

TL;DR: The Pinus contorta var, latifolia was experimentally introduced in Sweden already in the 1920s, and has been used in Swedish forestry on a large scale since the 1970s.

TL;DR: Magnesium (Mg) nutrition and photosynthesis were studied in clones of Pinus radiata D. Don grown in sand culture for 21 weeks and found significant clonal variation in Mg nutrition of P. radiata.
Abstract: Magnesium (Mg) nutrition and photosynthesis were studied in clones of Pinus radiata D. Don grown in sand culture for 21 weeks at four Mg concentrations (0.008, 0.04, 0.2 and 0.4 mM) and three potassium (K) concentrations (0.25, 0.5 and 2.5 mM). We found significant clonal variation in Mg nutrition of P. radiata. Plants grown at 0.04 mM [Mg] or less showed pronounced visible symptoms of foliar Mg deficiency. Net photosynthetic rate and leaf conductance were closely related to shoot Mg concentrations below a concentration of 0.6 mg Mg g(DW) (-1). Potassium enhanced the development of visible symptoms of foliar Mg deficiency. At the lowest Mg concentration tested (0.008 mM), the severity of needle chlorosis and necrosis increased with increasing K concentration in the culture solution. With increasing Mg concentration, 2.5 mM [K] in the culture solution markedly increased root Mg concentration, but decreased shoot Mg concentration, suggesting that excessive K inhibited Mg mobilization from roots to shoots. Rates of growth and photosynthesis were both severely inhibited at 0.008 mM [Mg].

TL;DR: Mosses, lichens and pine bark were compared as indicators of atmospheric heavy metal deposition in Finland as mentioned in this paper, where the major emission sources and the areas affected were reflected in the metal concentrations in the samples.
Abstract: Mosses, lichens and pine bark were compared as indicators of atmospheric heavy metal deposition in Finland. The samples were collected from the nationwide sampling network systematically covering the country as a whole. All three bioindicators showed a fairly similar result concerning heavy metal deposition. The major emission sources and the areas affected were reflected in the metal concentrations in the samples. However, there were differences between the accumulation of metals. The correlation between concentrations in mosses and lichens was generally higher than that between mosses and bark or lichens and bark. Concentrations in lichens were the highest and lichens reflected the regional differences in background areas as well as the local emission sources. The concentrations in the mosses were slightly lower than those in lichens and also the mosses pinpointed the emission sources and the extend of the areas polluted. Bark had the lowest concentrations and bark did not generally reveal regional differences as well as mosses and lichens. In spite of the differences, all three bioindicators proved to be suitable for monitoring atmospheric heavy metal deposition.
